An Innovative Architecture for Resilient Timing

Critical infrastructures for communications, transportation, energy and data centers need accurate and precise clocks. The Virtual Primary Reference Time Clock (vPRTC) is a highly secure and resilient network-based timing architecture that has been developed to meet the expanding needs of modern critical infrastructures, including 5G, transportation, data centers and power utilities.

This resilient architecture alleviates dependency on satellite-based timing sources such as Global Navigation Satellite Systems (GNSS) by placing the autonomous time-scale-grade atomic clocks in Enhanced Primary Reference Time Clock (ePRTC) area timing-hub sites at the core of a fiber-based terrestrial timing distribution network. Secure core-timing sites and fiber distribution are 100% in control of the network operator and immune to potential jamming or spoofing cyberattacks on satellite-based timing solutions. The vPRTC resilient timing architecture has been deployed across a wide range of industries with millions of hours of cumulative operation. Discover more below.
